Patent GB-2211577-A (GB)
Title: A clutch control system
Inventor: PARSONS DAVID
IPC: F16D29/00
Filed: 1987-10-26
Abstract: The system comprises a master cylinder 10 which is driven by an electric motor 14. A slave cylinder 18 is operable in response to the master cylinder to operate a motor vehicle clutch 22. A non return valve 24 is provided in a fluid line 17 between the master cylinder and the slave cylinder. The non-return valve 24 inhibits return flow of fluid from the slave cylinder to hold the clutch in a released condition so that the release condition is maintained by a low motor current. There is preferably also a bypass valve (25) bypassing the non-return valve to allow clutch engagement. The motor and the bypass valve are preferably controlled by a central module according to parameters such as engine speed and master cylinder piston position. <IMAGE>

Title: Method for making paintings
Inventor: HASSALL JOHN GRAHAM
IPC: B44F9/12
Filed: 1987-11-05
Abstract: Basic pictorial content is provided on a uniform dark (e.g. black) coloured varnish surface of a support board by application of a lighter (e.g. white) coloured base layer. The surface of the board being embossed so as to have a grained appearance, preferably resembling leather, and Translucent colour washes (e.g. red, blue, yellow) are subsequently applied over all or only part of the board surface for the purpose of colouring in the plain base layer in any manner desired by the end user. No great care is required in application of these colour washes; it is expected that they will overlap onto the remaining dark varnish coating, but due to the dark, glossy and grained nature of this area the regions covered by the washes and particularly their edges are not visible. Moreover, as the surface is glossy and does not immediately absorb the wash errors can readily be put right.
Patent GB-2214560-A (GB)
Title: Lock keeps
Inventor: LEWIS ROGER CHARLES
IPC: E05B17/00
Filed: 1988-01-25
Abstract: A lock keep (28) for use with bolt locks (25) has a keep member (29) which is movable against a bias (39) from a normal position, defined by a stop (37) in which the keep member forms a locking side of a recess in the keep for receiving a projecting end portion (26) of the bolt tongue (25), to a displaced position in the recess (shown in Fig.3). If a door (18) carrying the bolt (25) is slammed into its closed position against a stop (20) with the bolt (25) in its fully projecting position, the projecting tongue (26) moves the keep member (29) against the bias (39), into its displaced position, without damage to the bolt or keep. <IMAGE>

Patent GB-2204437-A (GB)
Title: Display apparatus
Inventor: SINGLETON ANTHONY JAMES
IPC: G09F11/02
Filed: 1988-05-06
Abstract: A display apparatus uses rotatable prisms to create a variable composite display. Each prism has individually removable faces 24 mounted to a central carrier 26, 28. A mounting means 40 is resiliently displaceable in the longitudinal direction. This can permit removal of a face 24 without using tools and can maintain a face under tension and take up expansion and contraction (which is particularly important for a translucent plastics face of a prism containing a light source 36). The carrier may have a spaced pair of coaxial hubs 26, 28, with a retainer plate 40 having a radially extending hooked arm 44, 46 for engaging a slot 58 in each face 24. One plate 40 may be resiliently displaceable, e.g. being mounted to its hub by long bolts 52 along which it is displaceable, the bolts 52 bearing springs 54 to restrain the displacement Alternatively (Fig. 9) a prism is a tubular unit (62) suspended from an upper hub (64) passing slidably over a lower hub (66) to allow for expansion and contraction. Release of the prism from the upper hub (64) allows it to drop down around the lower hub (66), whose shape allows tilting to give access to interior fittings (80, 82) and removal of an entire prism. <IMAGE>

Title: Devices for triggering inflation valves
Inventor: RAEBURN MICHAEL
IPC: B63C9/18
Filed: 1992-07-04
Abstract: A device for triggering an inflation valve comprises an abutment (20) and a piston (18) adapted to be attached to the inflation valve. A handle (28) is movable relative to the abutment (20) between first and second positions, and urging means (22) for urging the piston (18) towards the abutment (20) is connected between the piston (18) and the handle (28) and applies insufficient forces to the piston (18) to trigger the valve when the handle (28) is in the first position. A collapsible member (16), which collapses on contact with water, is arranged between the piston (18) and the abutment (20). Movement of the handle (28) to the second position increases the urging force of the urging means (22) on the piston (18) to move the piston (18) towards the abutment (20) upon collapse of the collapsible member (16). <IMAGE>

Title: Oil well production system.
Inventor: SAUER CARL W
IPC: E21B43/12
Filed: 1992-07-09
Abstract: A production system 10 for a subsea well 12 includes a concentric gas lift string 40 and a production tubing string 38 both located within a production riser 30. Lift gas injected down the annulus 42 between the production tubing string 38 and gas tubing string 40 is injected into the production tubing string 38 below the mud line 14 and thus provides gas lift assistance to the produced fluid stream 138. Thus increased produced fluid flow is provided while simultaneously insulating the produced fluid 136 from the surrounding ocean 16 thus maintaining the temperature of the produced fluid 136 which aids separator efficiencies once the produced fluid 136 reaches a surface platform 24 associated therewith. The use of the concentric gas tubing string 40 avoids pressurizing of the production riser 30. A gas lift mandrel 36, and associated apparatus 86, 92 are provided at the subsurface tubing hanger 32 to permit gas to be selectively directed down to a lower gas lift valve located deeper within the well. <IMAGE>
